When buying a guinea pig it will be necessary to purchase equipment such as guinea pig hutch or indoor cage, water bottle, food dish, woodshavings, hay, and food. A guinea pig hutch will cost £60 – £300 and a indoor cage £30 – £80. If the hutch does not include a run, a separate outside run can cost £60 – £100. Other equipment can cost £20 – £40.
The guinea pig will need a grain or pellet diet and hay and this can cost approximately £10 – £15 per month.
In addition a guinea pig will need to be fed vegetables and unless growing your own all year round, these will need to be bought and can cost an extra £10 – £15 per month.
Woodshavings will be needed to cover the floor of the hutch or cage and can cost £5 – £15 per month depending on the size of cage or hutch.
Although the main regular costs of keeping a guinea pig are listed above there are always unexpected costs that occur. In addition it is often necessary to purchase health products for minor ailments, replace equipment, etc. All such costs can mount up over a year. Therefore it is always best to factor in an additional cost of £100 – £150 per annum for extras when working out whether keeping a guinea pig can be afforded.
The table below gives a summary of the costs involved in keeping one guinea pig. If keeping more than one guinea pig together, as it is recommended to do, then the costs will be double with the exception of the equipment costs as the guinea pigs will share equipment although these costs will be towards the higher end of the range given as a large hutch would need to be purchased.
